Near the closure of the elections, the chances between the two candidates becomes 50/50. So odds for Clinton will become around 2.0. Currently her odds are between 1.4/1.5. Therefore, it's a good idea to bet against Clinton to become president. You can sell your bet near the elections at 2.0.
I think it's best to bet when it's nearly couple of weeks before the election starts to make a much overview in the polls. And yes I sees it's a good idea to bet against Clinton.
Anyways is there a bitcoin gambling site where we can bet for those US presidential candidates?
